Hadalpelagic Zone

Hadal Zone

Ocean trenches deeper than 6000m - the deepest habitats on Earth, including the Mariana Trench at 11,000m.

Depth: 6,000-11,000m Light: None Pressure: 600-1100 atm Temp: 1-4

📖 Overview

Hadal trenches are the deepest ocean environments - the Mariana Trench reaches nearly 11,000 meters. Pressures are over 1,000 times atmospheric. Life exists but is highly specialized: hadal snailfish, amphipods, and unique bacterial communities dominate. Scientific submersibles reach these depths only rarely.
